Technical FAQs 4

Can battery energy storage improve frequency modulation of thermal power units?

Li Cuiping et al. used a battery energy storage system to assist in the frequency modulation of thermal power units, significantly improving the frequency modulation effect, smoothing the unit output power and reducing unit wear.

What is dynamic frequency modulation model?

The dynamic frequency modulation model of the whole regional power grid is composed of thermal power units, energy storage systems, nonlinear frequency difference signal decomposition, fire-storage cooperative fuzzy control power distribution, energy storage system output control and other components. Fig. 1.

What is the frequency modulation of hybrid energy storage?

Under the four control strategies of A, B, C and D, the hybrid energy storage participating in the primary frequency modulation of the unit |Δ fm | is 0.00194 p.u.Hz, excluding the energy storage system when the frequency modulation |Δ fm | is 0.00316 p.u.Hz, compared to a decrease of 37.61 %.

How to evaluate frequency modulation performance under a control strategy?

Similarly, under external perturbations, the frequency modulation power change evaluation method is similar to frequency, the corresponding average value of power fluctuation is adopted Pm, power peak difference Δ P, the overall degree of power fluctuation Psd evaluates the frequency modulation performance under the corresponding control strategy.
